Your Strategic Partner for Precision Tubing Technology and Quality Assurance

The quality of the tubing directly impacts refrigerant circulation efficiency and system failure rates. We ensure our professionalism and industry authority through the following key aspects:
Internal Cleanliness Control

All our Copper Capillary Tube and Bundy Tube products undergo professional cleaning and drying treatment, strictly controlling internal residue to prevent blockages and ensure the flow accuracy of the Refrigeration Copper Capillary Tube.

High Pressure Resistance and Anti-Corrosion

Our Refrigeration Bundy Tube can be supplied with various anti-corrosion coatings, featuring excellent weather resistance. The outer material of the Insulated Copper Tube features Resistant Insulated Copper Tube characteristics.

Integrated Production

We possess a complete production chain from raw materials to finished tubing, ensuring outstanding dimensional consistency and mechanical properties for both single-layer Bundy Tube and double-layer tubes.

Bundy Tube Series - Strength and Application Foundation

1.Bundy Tube Series: Core Tubing for Wire Tube Condenser and Automotive Brake Systems

Bundy Tube possesses excellent pressure resistance and sealing due to its unique double-wall brazed structure.

Bundy Tube

A highly reliable steel tube widely adopted in the refrigeration and automotive industries.
● Core Product: Bundy Tube. It is a steel double-wall brazed tube extensively used for transferring refrigerants and brake fluids.
● Refrigeration Application: We specialize in manufacturing Refrigeration Bundy Tube, particularly suitable for the production of the Bundy Tube Wire Tube Condenser.
● Material Extension: For specific applications, we offer Copper Bundy Tube, which combines the superior thermal conductivity of copper with the structural strength of a Bundy tube.

2.Bundy Tube Series: Core Tubing for Wire Tube Condenser and Automotive Brake Systems

The copper capillary tube is a key component in small refrigeration equipment, replacing the expansion valve to achieve throttling and pressure reduction.

Refrigeration Copper Capillary Tube

The core throttling tube ensuring precise refrigerant flow matching.
● Core Products: Copper Capillary Tube and Refrigeration Copper Capillary Tube.
● Manufacturing Process: We offer various conditions to meet customer requirements for rigidity and flexibility, including high-flexibility Annealed Copper Capillary Tube and high-precision Drawn Copper Capillary Tube. Some models also feature Coated Copper Capillary Tube for added corrosion resistance.
● Size Customization: We can precisely control various Copper Capillary Tube Size specifications, from minimal inner diameters to exact lengths, ensuring throttling accuracy.

3. Insulated Copper Tube Series: Professional Connection Solutions for AC and Heat Pump Systems

Air Conditioner Insulated Copper Tube

An integrated insulation solution that effectively reduces energy loss.
● Core Product: Insulated Copper Tube. Specifically designed to reduce condensation or frost formation.
● Application Focus: Our tubing is dedicated to Conditioning Insulated Copper Tube and Air Conditioner Insulated Copper Tube systems.
● Insulation Features: The insulation layer uses high-quality material with Resistant Insulated Copper Tube properties, providing long-lasting thermal protection. It is typically supplied in the form of Wrapped Insulated Copper Tube.

Mixed Applications of Brass and Copper and System Upgrade Solutions

We understand that transitional connections of different materials may be required in complex system maintenance and upgrades.

Frequently Asked Questions for Refrigeration Tubing Bulk Procurement

Q: What are the internal cleanliness standards for your Refrigeration Bundy Tube and Copper Capillary Tube?
A: We enforce strict industry standards, ensuring that internal residues (such as oil or moisture) in all Refrigeration Bundy Tube and Copper Capillary Tube are far below industry requirements, guaranteeing the clean circulation of refrigerant.
A: The selection of Copper Capillary Tube Size is based on cooling capacity, condensing temperature, and evaporating temperature. Our engineering team can assist you in determining the optimal inner diameter and length of the Drawn Copper Capillary Tube based on your system design parameters.
A: Our Air Conditioner Insulated Copper Tube uses high-density weatherproof materials, possessing Resistant Insulated Copper Tube properties. It effectively resists UV rays, high humidity, and temperature variations, ensuring the Wrapped Insulated Copper Tube maintains its long-term thermal performance even in outdoor installations.
A: Bundy Tube is primarily made of steel, offering high strength and lower cost, often used in applications that do not require extremely high thermal conductivity (like the Bundy Tube Wire Tube Condenser) or require high pressure resistance. In situations demanding high thermal conductivity or specific brazing requirements, Copper Bundy Tube may be more suitable; this must be evaluated based on the specific application.
